Cooperative Classrooms Lead To Better Friendships, Higher Achievement In Young Adolescents:

Students competing for resources in the classroom while discounting each others’ success are less likely to earn top grades than students who work together toward goals and share their success, according to an analysis of 80 years of research.

Despite Awareness Of Global Warming Americans Concerned More About Local Environment:

British Prime Minister Gordon Brown recently declared climate change a top international threat, and Al Gore urged politicians to get involved to fight global warming. Results from a recent survey conducted by a University of Missouri professor reveal that the U.S. public, while aware of the deteriorating global environment, is concerned predominantly with local and national environmental issues.

Systems Biology Approach Identifies Nutrient Regulation Of Biological Clock In Plants:

Using a systems biological analysis of genome-scale data from the model plant Arabidopsis, an international team of researchers identified that the master gene controlling the biological clock is sensitive to nutrient status. This hypothesis derived from multi-network analysis of Arabidopsis genomic data, and validated experimentally, has shed light on how nutrients affect the molecular networks controlling plant growth and development in response to nutrient sensing.

Weight Bias Is As Prevalent As Racial Discrimination, Study Suggests:

Discrimination against overweight people–particularly women–is as common as racial discrimination, according to a study by the Rudd Center for Food Policy & Obesity at Yale University.

Why Don’t Kids Walk To School Anymore?:

According to a University of Michigan researcher, concerns about safety are the main reason that less than 13 percent of U.S. children walked or biked to school in 2004, compared to more than 50 percent who did so in 1969.
